ITEM 1.  BUSINESS


THE COMPANY

     Somanetics Corporation ("Somanetics" or the "Company") was incorporated in
1982 and develops, manufactures and markets the INVOS(R) Cerebral Oximeter (the
"Cerebral Oximeter"), the only FDA-cleared, non-invasive patient monitoring
system that continuously measures changes in the blood oxygen level in the
adult brain. The Cerebral Oximeter was developed to meet the need for
information about oxygen in the brain, the organ least tolerant of oxygen
deprivation. Brain oxygen information, therefore, is important, especially in
surgical procedures requiring general anesthesia and in other critical care
situations with a high risk of brain oxygen imbalances. The Company is
initially targeting cardiovascular and vascular surgeries and surgeries on
elderly patients involving abnormal blood pressure, because these surgeries
involve a high risk of brain oxygen imbalances, both during and after surgery.
Surgeons, anesthesiologists and other medical professionals use the Cerebral
Oximeter to identify brain oxygen imbalances and take corrective action,
potentially improving patient outcome and reducing the cost of care.

     The Cerebral Oximeter is a relatively inexpensive, portable and
easy-to-use monitoring system placed at a patient's bedside in hospital
critical care areas, especially operating rooms, recovery rooms, intensive care
units ("ICUs") and emergency rooms. It is comprised of (i) a portable unit
including a computer and a display monitor, (ii) a single-use, disposable
sensor, the SomaSensor(R), (iii) proprietary software and (iv) a preamplifier
cable. The SomaSensor is adhered to a patient's forehead and connected to the
computer through the preamplifier cable. The computer uses the Company's
proprietary software to analyze information received from the SomaSensor and
provides a continuous digital and trend display on the monitor of an index of
the oxygen saturation in the area of the brain under the SomaSensor. Users of
the Cerebral Oximeter will be required to purchase disposable SomaSensors on a
regular basis because of their single-use nature.

     In October 1997, the Company obtained FDA clearance for new advances in
its INVOS technology that are incorporated in its next generation Cerebral
Oximeter.  The next generation Cerebral Oximeter was introduced in October 1997
at two industry trade shows and is expected to be available in the first
quarter of fiscal 1998.  The Company's objective is to establish the Cerebral
Oximeter as a "standard of care" in surgical procedures requiring general
anesthesia and in other critical care situations.


MARKET OVERVIEW

INDUSTRY BACKGROUND

     The brain is the human organ least tolerant of oxygen deprivation. Without
sufficient oxygen, brain damage may occur within a few minutes, which can
result in paralysis, severe and complex disabilities or death. Undetected brain
hypoxia (insufficiency of oxygen delivery) and ischemia (tissue oxygen
starvation due to the obstruction of the inflow of arterial blood) are common
causes of brain damage and death during and after many surgical procedures and
in other critical care situations. A December 1996 article in The New England
Journal of Medicine reported on a 24-institution study and concluded that
adverse cerebral outcomes after coronary artery bypass graft surgery are
relatively common and serious and are associated with substantial increases in
death, length of hospitalization and use of intermediate- or long-term care
facilities. Adverse cerebral outcomes occurred in 6.1% of the patients included
in the study. Additional studies have estimated that a higher percentage of
patients experience some neurological decline after heart surgery and that
insufficiency of oxygen delivery to the brain is a frequent cause of this
problem. The New England Journal article concluded that new diagnostic and
therapeutic strategies must be developed to lessen such injury.


                                       2

     Oxygen is carried to the brain by hemoglobin in the blood. Hemoglobin
passes through the lungs, bonds with oxygen and is pumped by the heart through
arteries and capillaries to the brain. Brain cells extract the oxygen and the
blood carries away carbon dioxide through the capillaries and veins back to the
lungs. Brain oxygen imbalances can be caused by several factors, including
changes in oxygen saturation (the percentage of hemoglobin contained in a given
amount of blood which carries oxygen) in the arteries, blood flow to the brain,
hemoglobin concentration and oxygen consumption by the brain.

     Brain oxygen information is important in surgical procedures requiring
general anesthesia, in other critical care situations with a high risk of brain
oxygen imbalances, as well as in the treatment of patients with head injuries
or strokes. These procedures include cardiovascular and vascular surgeries,
surgeries on elderly patients involving abnormal blood pressure, any
neurosurgery, major surgeries involving the neck, transplant surgeries and
treatment of patients with diseases resulting from high blood pressure, lung
problems, or head, organ or heart injuries and treatment of patients suffering
from strokes. These patients are most commonly found in operating rooms as well
as in the other critical care areas of hospitals, especially recovery rooms,
ICUs and emergency rooms. The Company believes that medical professionals need
immediate and continuous information about changes in the oxygen levels in the
blood in the brain to identify brain oxygen imbalances. After they are alerted
to such imbalances, medical professionals have the information to take
corrective action through the introduction of medications, anesthetic agents or
mechanical intervention, potentially improving patient outcome and reducing the
costs of care. Immediate and continuous information about changes in brain
oxygen levels also provides immediate feedback regarding the adequacy of the
selected therapy. Equally important, without information about brain oxygen
levels, therapy that may not be necessary might be initiated to assure adequate
brain oxygen levels. Unnecessary therapy can have an adverse impact on patient
safety and increase hospital costs.

     Based on a 1995 survey, industry sources estimate that more than 24
million surgeries were performed in the United States. Industry sources also
estimate that, in 1993, there were more than 4.4 million surgeries involving
the heart or the blood vessels around the heart. Such surgeries include more
than 600,000 open heart surgeries and 89,000 endarterectomies (the removal of
blockage in the artery). Industry sources estimate, based on a 1985 survey,
that there were more than 26,800 operating rooms in the United States and,
based on a 1993 survey, that there were more than 6,100 ICUs in the United
States with more than 90,000 beds.

     Currently, several different methods are used to detect one or more of the
factors affecting brain oxygen levels or the effects of brain oxygen
imbalances. These methods include invasive jugular bulb catheter monitoring,
transcranial Doppler, electroencephalograms ("EEG"), intracranial pressure
monitoring and neurological examination. These methods have not been widely
adopted to monitor brain oxygen levels in critical care situations for a
variety of reasons. The use of any of these methods is limited because it is
either expensive, difficult or impractical to use as a brain monitor, invasive,
not available under certain circumstances (such as when the patient is
unconscious or has suppressed neural activity), not able to measure all of the
factors that may affect brain oxygen imbalances, not organ specific or not able
to provide continuous information or able to measure only the effects of brain
oxygen imbalances.

     Arterial oxygen saturation is only one of the factors that can affect
oxygen imbalances in the brain. Pulse oximetry measures oxygen saturation in
the arteries. It is non-invasive, uses optical spectroscopy and has become a
standard of care for measuring arterial oxygen saturation in critical care
situations. However, pulse oximeters require a strong pulse, making them
unavailable during bypass surgeries, surgeries involving induced hypothermia or
any other time the patient does not have a strong peripheral pulse. Pulse
oximeters provide information about the oxygen saturation of the arteries in a
finger or earlobe, not oxygen imbalances in the brain. Changes in the oxygen
balance in the brain may not have any affect on the oxygen levels in a finger
or earlobe. For example, a blocked artery to the brain would affect oxygen in
the brain, but would not affect the amount of oxygen in the arteries in the
finger.

     The Cerebral Oximeter is the only FDA-cleared, non-invasive monitoring
system that provides continuous information about changes in the blood oxygen
level in the adult brain. It is easy to use and relatively inexpensive and
provides medical professionals with new information to help them identify brain
oxygen imbalances. This information may facilitate timely intervention, provide
feedback regarding the adequacy of the selected therapy and provide medical
professionals with additional assurance when they make decisions regarding the
need for therapy, thereby potentially improving patient outcome and reducing
the cost of care.

MARKET TRENDS

     The Company believes the market for its product is driven by the following
market trends:

     Demand to Reduce Health Care Costs. Hospitals in the United States are
increasingly faced with direct economic incentives to control health care costs
and improve the efficiency of health care through improved labor productivity,
shortened hospital stays and more selective performance of medical procedures
and use of facilities and equipment. Hospitals often receive a fixed fee from
Medicare, managed care organizations and private insurers based on the disease
diagnosed, rather than based on the services actually performed. Therefore,
hospitals are increasingly focused on avoiding unexpected costs, such as those
associated with increased hospital stays resulting from patients with brain
damage or other adverse outcomes following surgery. This focus on avoiding
unexpected costs is especially pronounced in the operating room and other
hospital critical care areas due to their high operating costs. The economic
and human costs of brain damage can be tremendous. Even short extensions of
hospital stays resulting from brain damage can be expensive. In addition,
overtreating a patient as a result of lack of knowledge about brain oxygen
levels can result in unnecessary costs.

     Organ-Specific Monitoring; Current Emphasis on the Brain. The Company
believes that physicians and hospitals are increasingly interested in
monitoring the status of specific organs in the body, especially the brain. It
also believes there is an increased interest in understanding how the brain
functions and in finding ways to prevent injury to, and cures to diseases
affecting, the brain. The Company believes that this interest has led to a
greater focus on monitoring the brain, both to determine how it functions and
to monitor the effects of various actions on the brain. In July 1989, Congress
passed a resolution, and President Bush signed a proclamation, designating the
1990s as the "Decade of the Brain."

     Less Invasive Medical Procedures. The Company believes there is a trend
toward less invasive medical procedures. Notable examples include laparoscopic
procedures in general surgery and arthroscopic procedures in orthopedic
surgery. Such procedures are designed to reduce trauma, thereby decreasing
complications, reducing pain and suffering, speeding recovery and decreasing
costs associated with patient care. The Company also believes that there is a
trend to minimize invasive procedures relating to the brain to increase the
safety of patients and medical professionals, reduce recovery time and minimize
costs.

     Aging Population. According to the Administration on Aging, United States
Department of Health and Human Services, approximately 33.5 million persons in
the United States were age 65 or older in 1995, representing 13% of the
population. The number of Americans age 65 or older increased by approximately
2.3 million, or 7%, between 1990 and 1995, compared to an increase of 5% for
the under-65 population. The Administration on Aging predicts that the number
of Americans age 65 or older will increase to approximately 34.7 million by the
year 2000 and to approximately 53.2 million by the year 2020. The Company
believes that older patients require a higher level of medical care using more
procedures in which the patient or the procedure involves a risk of brain
oxygen imbalances. Medical and surgical procedure growth rate has remained
steady recently, and industry analysts expect this trend to continue.

BUSINESS STRATEGY

     The Company's objective is to establish the Cerebral Oximeter as a
"standard of care" in surgical procedures requiring general anesthesia and in
other critical care situations. Key elements of the Company's strategy are as
follows:

     Target Surgical Procedures With a High Risk of Brain Oxygen Imbalances.
The Company is targeting its initial marketing efforts primarily on the use of
the Cerebral Oximeter in surgical procedures with a high risk of brain oxygen
imbalances, such as cardiovascular and vascular surgeries and surgeries on
elderly patients involving abnormal blood pressure. The Company believes that
the medical professionals involved in these surgeries are the most aware of the
risks of brain damage resulting from brain oxygen imbalances. Therefore, the
Company believes that it will be easier to demonstrate the clinical benefits of
the Cerebral Oximeter and potentially gain market acceptance for its product in
connection with these surgeries.


                                       4



<PAGE>   6


     Demonstrate Clinical Benefits and Promote Acceptance of the Cerebral
Oximeter. The Company sponsors clinical studies using the Cerebral Oximeter to
provide additional evidence of its benefits. The resulting publication of any
favorable peer-reviewed papers is used to help convince the medical community
of the clinical benefits of the Cerebral Oximeter. The Company also promotes
acceptance of the Cerebral Oximeter in the medical community by encouraging
surgeons, anesthesiologists and nurses in leading hospitals, whose opinions and
practices the Company believes are valued by other hospitals and physicians, to
use the Cerebral Oximeter on a trial basis. The Company believes that
successful evaluations of the Cerebral Oximeter by these medical professionals
will accelerate the acceptance of the Cerebral Oximeter by other medical
professionals. The Company sponsors discussions among physicians who have used
the Cerebral Oximeter about its clinical benefits.

     Expand Marketing and Sales Activities. The Company has recently
established a distribution network consisting of its direct sales employees and
distributors. The Company is expanding its marketing and sales efforts to
increase the medical community's exposure to its INVOS technology and the
Cerebral Oximeter, including increased participation in trade shows and medical
conferences and increased product evaluations. The Company is aggressively
marketing its product through its existing sales force and leverages its sales
resources through the use of its distributors, including Baxter Limited in
Japan.

     Develop Additional Applications of the Cerebral Oximeter. The Company is
in the process of developing product-line extensions of the Cerebral Oximeter
for use on children and newborns. The Company believes that these natural
extensions of its existing product will increase the market for the Cerebral
Oximeter without the more significant development efforts required for entirely
new products. The Company believes that non-invasive monitoring is important
for newborns, as they have higher risks of oxygen imbalances and less blood
volume from which medical professionals can make invasive blood gas
measurements.

     License Technology to Medical Device Manufacturers. The Company plans to
license its Cerebral Oximeter technology to other medical device manufacturers
to expand the installed base of Cerebral Oximeters and increase the demand for
SomaSensors. Such a license might be made to a company interested in
incorporating the Cerebral Oximeter into a multi-function monitor. The Company
believes that such an arrangement could provide another distribution channel
for the Company's Cerebral Oximeter. The Company, however, has no current
commitments for any such licenses.

     In addition, the Company is analyzing the feasibility of other
applications of its technology. The Company has entered into a consulting
arrangement with NeuroPhysics Corporation in connection with research into the
feasibility of four new products.

PRODUCT AND TECHNOLOGY

THE CEREBRAL OXIMETER

     The Company's Cerebral Oximeter is the only FDA-cleared, non-invasive
patient monitoring system that provides continuous information about changes in
the blood oxygen level in the adult brain. It is a portable and easy-to-use
monitoring system that is placed at a patient's bedside in hospital critical
care areas, especially operating rooms, recovery rooms, ICUs and emergency
rooms. Surgeons, anesthesiologists and other medical professionals use the
information provided by the Cerebral Oximeter to identify brain oxygen
imbalances and take corrective action, potentially improving patient outcome
and reducing the cost of care. Once the cause of a cerebral oxygen imbalance is
identified and therapy is initiated, the Cerebral Oximeter provides immediate
feedback regarding the adequacy of the selected therapy. It can also provide
medical professionals with an additional level of assurance when they make
decisions regarding the need for therapy.

     Unlike certain existing monitoring methods, the Cerebral Oximeter
functions even when the patient is unconscious, lacks a strong peripheral pulse
or has suppressed neural activity. The measurement made by the Cerebral
Oximeter is dominated by the blood in the veins. Therefore, it responds to the
changes in factors that affect the balance between cerebral oxygen supply and
demand, including changes in arterial oxygen saturation, cerebral blood flow,
hemoglobin concentration and cerebral oxygen consumption. The Cerebral Oximeter
responds to global changes in brain oxygen levels and to events that affect the
brain oxygen levels in the region beneath the SomaSensor.

                                       5



<PAGE>   7



     The Cerebral Oximeter monitoring system is comprised of (i) a portable
unit including a computer and a display monitor, (ii) a single-use, disposable
sensor, the SomaSensor, (iii) proprietary software and (iv) a preamplifier
cable. The SomaSensor is adhered to a patient's forehead and connected to the
computer through the preamplifier cable. The SomaSensor continuously transmits
and receives predetermined wavelengths of light sent through the scalp, muscle
and skull into the brain tissue. The computer receives the information about
the intensity of the light scattered by the blood and tissue in the area being
monitored. The computer uses the Company's proprietary software to analyze this
information and provide a continuous digital and trend display on the monitor
of an index of the oxygen saturation in the area of the brain under the
SomaSensor.

     The portable unit includes a menu-driven user interface which provides
easy access for setting high and low audible alarms and permits a customized
display format and data retrieval. Single-function keys offer a convenient
means of powering the Cerebral Oximeter, silencing alarms, marking important
events and printing results that can be stored for up to 24 hours and retrieved
by a variety of standard, commercially available printers.  The next generation
Cerebral Oximeter measures approximately 9 inches wide, 8 inches high, and 8
inches deep and weighs approximately 15 pounds.

     The suggested list prices for the next generation Cerebral Oximeter and
the SomaSensor in the United States are $11,995 and $35, respectively. Users of
the Cerebral Oximeter will be required to purchase disposable SomaSensors on a
regular basis. The SomaSensor may only be used once because after one use it
may become contaminated and its effectiveness is not warranted by the Company.
The Company provides a one-year warranty on the Cerebral Oximeter, which the
Company will satisfy by repairing or exchanging those units in need of repair.
The Company also expects to offer maintenance agreements and service for the
Cerebral Oximeter for a fee after the warranty expires.

     The following table summarizes the principal features and related benefits
of the Cerebral Oximeter:

OPTICAL SPECTROSCOPY TECHNOLOGY

     The Company's proprietary In Vivo Optical Spectroscopy ("INVOS")
technology is based primarily on the physics of optical spectroscopy. Optical
spectroscopy is the interpretation of the interaction between matter and light.
Spectrometers and spectrophotometers function primarily by shining light
through matter and measuring the extent to which such light is transmitted
through, or scattered or absorbed by, matter. Physicians and scientists can use
spectrophotometers to examine human blood and tissue. Although most human
tissue is opaque to ordinary light, certain wavelengths penetrate tissue more
easily than others. Therefore, by shining light of appropriate wavelengths into
the body and measuring its transmission, scattering and absorption, or a
combination, physicians can obtain information about the matter under analysis.
Optical spectroscopy generates no ionizing radiation and produces no known
hazardous effects.

     Optical spectroscopy was first used clinically in the 1940s at the
Sloan-Kettering Institute for cancer research. The pulse oximeter uses optical
spectroscopy to determine the oxygen saturation of the blood in the arteries in
peripheral tissue, such as in a finger or an earlobe. By identifying the
hemoglobin and the oxygenated hemoglobin and measuring the relative amounts of
each, oxygen saturation of hemoglobin can be measured. However, the use of
optical spectroscopy in the body has not generally been useful when the
substances to be measured are surrounded by, are behind, or are near bone,
muscle or other tissue, because the transmission, scattering and absorption of
the transmitted light produces extraneous data that interferes with analysis of
the data from the area being examined.

INVOS TECHNOLOGY

     The Cerebral Oximeter is based on INVOS technology. In 1982, the Company
commenced research and development efforts in connection with a spectroscopic
instrument for the measurement of breast tissue abnormalities. The Company's
first product, the Somanetics INVOS 2100 System (the "INVOS 2100"), used the
same INVOS technology as the Cerebral Oximeter. Subsequently, the Company
commenced analysis of the application of INVOS technology to the measurement of
changes in cellular metabolism in the brain. Early studies conducted in
conjunction with the Henry Ford Neurosurgical Institute demonstrated the
ability of the Company's INVOS technology to make certain measurements which
were highly correlated to controlled changes in animal brain cell metabolism.
In 1988, the Company began clinical studies of the Cerebral Oximeter on human
patients in operating rooms, emergency rooms and ICUs at Henry Ford Hospital
and later at Bowman Gray School of Medicine and Mount Sinai Medical Center.

     Like other applications of optical spectroscopy, INVOS technology also
analyzes various characteristics of human blood and tissue by measuring and
analyzing low-intensity visible and near-infrared light transmitted into
portions of the body. It measures the composition of substances by detecting
the effect they have on light. The INVOS technology measurement is made by
transmitting low-intensity visible and near-infrared light through a portion of
the body and detecting the manner in which the molecules of the exposed
substance interact with light at specific wavelengths. INVOS technology detects
this interaction by measuring the intensity of the various wavelengths of light
received by light sensors. By measuring the effect on specific wavelengths of
light caused by oxygenated hemoglobin contained in blood in the region of the
brain being monitored, the Cerebral Oximeter can monitor changes in the
approximate oxygen saturation of the hemoglobin in such region of the brain.

     The Company has developed a method of reducing extraneous spectroscopic
data caused by surrounding bone, muscle and other tissue. This method allows
data to be gathered from areas of the body which previously could not be
analyzed using optical spectroscopy. The dual detector design of the SomaSensor
enables the measurement of scattered light intensities from the intermediate
tissues of skin, muscle and skull in a separate process. As illustrated above,
the depth of penetration of the light signal is related to the distance between
the light source and the shallow and deep detectors. While both detectors
receive similar information about the tissue outside the brain, the detector
further from the light source receives more information specific to the brain
than does the detector closer to the light source. By subtracting the two
measurements, INVOS technology is able to suppress the influence of the tissues
outside the brain to provide a measurement of changes in brain oxygen
saturation.

RESEARCH AND DEVELOPMENT

     The Company is currently focusing its research and development efforts on
product-line extensions of the Cerebral Oximeter for use on children and
newborns and enhancements to the SomaSensor.  The Company is currently
sponsoring clinical studies of the Cerebral Oximeter for use on children and
newborns, but expects to redesign the SomaSensor for use on smaller heads. The
Company believes that non-invasive monitoring is especially important in
newborns, who have higher risks of oxygen imbalances and less blood volume from
which medical professionals can make invasive blood gas measurements.

     In addition to the Company's internal research and development activities,
the Company has entered into a consulting arrangement with NeuroPhysics
Corporation pursuant to which the Company is funding a portion of NeuroPhysics'
research into the feasibility and development of prototypes of four new
products. The United States government is also funding a portion of the
research pursuant to two research grants. NeuroPhysics has granted the Company
certain ownership and commercialization rights in the new products, subject to
the rights of the United States government and royalties payable to
NeuroPhysics. The new products are intended to be non-invasive, in vivo,
near-infrared spectroscopy devices that (i) monitor liver oxygenation for
assessing and controlling hemorrhagic shock (shock resulting from loss of
blood), (ii) locate and assess subdural hematomas (bleeding between the brain
and the skull) in head trauma patients, (iii) monitor certain blood gasses and
(iv) monitor fetal cerebral blood oxygenation during labor and delivery.

     In October 1997, NeuroPhysics Corporation was awarded a $746,000 Phase II
contract from the National Institute of Neurological Disorders and Stroke of
the National Institutes of Health.  This award follows the completion of a
Phase I contract during which NeuroPhysics demonstrated the conceptual
feasibility of its noninvasive method for monitoring fetal cerebral oxygen
during labor and delivery.  The Phase II award will be used to continue the
development of this technology, assemble a prototype fetal cerebral oximeter
based on the new method, and conduct animal and human studies.  If Phase II is
successful, it is expected to be followed by the development of a product and
clinical trials in Phase III.

     During fiscal years 1997, 1996 and 1995 the Company spent $736,427,
$235,354 and $285,893, respectively, on research, development and engineering.

MARKETING, SALES AND DISTRIBUTION

MARKETING

     The Cerebral Oximeter is for use on patients at risk of brain oxygen
imbalances. These patients are most commonly found in operating rooms amongst
those undergoing general anesthesia for various surgical procedures as well as
in the other critical care areas of hospitals, especially recovery rooms, ICUs
and emergency rooms. After the Cerebral Oximeter is accepted in hospitals,
future markets might include free-standing operating rooms, clinics, ambulances
and nursing homes.

     The Company markets the Cerebral Oximeter primarily to cardiovascular and
vascular surgeons, neurosurgeons and anesthesiologists. The Company believes
that these specialists are the medical professionals most aware of the risks of
brain damage resulting from brain oxygen imbalances. The Company and its
distributors have initially concentrated on sales to the major teaching
hospitals in selected foreign markets in which the Company has commenced
commercial sales and the 2,000 largest United States hospitals, especially
those the Company considers opinion leaders. Product evaluations have already
begun at over 200 university and other hospitals. In addition, the Company is
sponsoring discussions among physicians who have used the Cerebral Oximeter
about its clinical benefits.

     The Company believes that favorable peer review is a key element to a
product's success in the medical equipment industry. Accordingly, the Company
supports clinical research programs with third-party clinicians and researchers
intended to demonstrate the need for, and clinical benefits of, the Cerebral
Oximeter with the specific objective of publishing the results in peer-reviewed
journals. The research consists primarily of comparing the measurements
obtained from the Cerebral Oximeter to the data obtained from existing
diagnostic methods,

                                       8



<PAGE>   10

including EEG, transcranial Doppler and invasive jugular bulb catheter
monitoring or reports of the results of the use of the Cerebral Oximeter in
various procedures. The Company attends trade shows and medical conferences in
order to introduce and promote the Cerebral Oximeter and to meet medical
professionals with an interest in submitting peer-reviewed papers to
appropriate medical journals and to major national meetings. In fiscal year
1997, a total of 37 presentations concerning the Cerebral Oximeter were
presented to 17 meetings, and 14 peer-reviewed articles (including three
presented at meetings) mentioning the Cerebral Oximeter were published.

SALES AND DISTRIBUTION

     The Company sells the Cerebral Oximeter through its direct sales force and
independent distributors. The Company has engaged distributors to provide it
with increased geographic coverage and local sales contacts. In the United
States, the Company sells the Cerebral Oximeter through its 19 direct
salespersons covering 19 states exclusively and 31 states and Puerto Rico in
which they support seven distributors. Sales compensation and incentive plans
are designed to motivate the Company's direct sales force by making half of
their targeted compensation dependent on meeting targeted sales levels. The
Company believes that the minimum selling cycle for new medical devices is
approximately six to nine months.

     In March 1997, the Company entered into a marketing arrangement with
Health Services Corporation of America, the representative of a buying group
for many small hospitals and extended care facilities. Health Services
Corporation of America informs its member hospital administrators that the
Company is its sole supplier of cerebral oximetry equipment and forwards the
Company's marketing materials to such administrators. In exchange, for its
marketing assistance, the Company's product will be available to the members of
the buying group at a discount.

     The Company's backlog of firm orders for its next generation cerebral
oximeter as of January 20, 1998 is a result of the time between the product's
introduction in October 1997 and its first shipment in the first fiscal quarter
of 1998.  The Company does not believe that its backlog is indicative of trends
in its business.

     Internationally, the Company has distribution agreements with 25
distributors covering 67 countries. In March 1995, the Company engaged Baxter
Limited as its exclusive distributor in Japan. In April 1995, Baxter Limited
was licensed by the Japanese Ministry of Health and Welfare (JMH&W) to market
the INVOS 3100A Cerebral Oximeter in Japan, and is in the process of applying
to the JMH&W to market the next generation Cerebral Oximeter there.  There can
be no assurance that the application will be approved prior to the fourth
quarter of fiscal 1998.

     For a description of sales to major customers, see Note 10 of Notes to
Financial Statements included in Item 8 of this Report.  The Company's
distributor in Japan was the Company's largest customer in fiscal 1997, 1996,
and 1995. The Company is dependent on its sales to Baxter Limited, and the loss
of Baxter Limited as a customer would have an adverse effect on the Company's
business, financial condition and results of operations.

     The Company's export sales for the fiscal years ended November 30, 1997,
1996 and 1995 were approximately $689,000, $745,000 and $1,336,000,
respectively. For a description of the breakdown of sales between model 3100A
Cerebral Oximeters, SomaSensors, and refurbished model 3100 Cerebral Oximeters,
see "Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Results of Operations."

MANUFACTURING

     The Company assembles the Cerebral Oximeter in its facilities in Troy,
Michigan, from components purchased from outside suppliers. The Company
assembles the Cerebral Oximeter to control its quality and costs and to permit
it to make changes to the Cerebral Oximeter faster than it could with
third-party assembly. The Company believes that each component is generally
available from several potential suppliers. The SomaSensor, the printed circuit
boards, other mechanical components and the unit enclosure are the primary
components that must be manufactured according to specifications provided by
the Company. Although the Company is currently dependent on one manufacturer of
the SomaSensor, the Company believes that several potential suppliers are
available to assemble the components of the Cerebral Oximeter. The Company
would, however, require approximately three to four months to change SomaSensor
suppliers. The Company does not currently intend to manufacture on a commercial
scale the disposable SomaSensor or the components of the Cerebral Oximeter.

COMPETITION

     The Company does not believe there is currently any direct commercial
competition for the Cerebral Oximeter. The Company believes, however, that the
market for cerebral oximetry products is in the early stages of its development
and, if it develops, may become highly competitive. The Company is aware of
foreign companies that have sold products relating to cerebral metabolism
monitoring for research or evaluation.

     The medical equipment industry is characterized by intense competition and
extensive research and development. Other companies and individuals are engaged
in research and development of non-invasive cerebral oximeters, and the Company
believes there are many other potential entrants into the market.  Some of
these potential competitors have well established reputations, customer
relationships and marketing, distribution and service networks, and have
substantially longer histories in the medical equipment industry, larger
product lines and greater financial, technical, manufacturing, research and
development and management resources than those of the Company. Many of these
potential competitors have long-term product supply relationships with the
Company's potential customers. These potential competitors may succeed in
developing products that are at least as reliable and effective as the
Company's product, that make additional measurements, or that are less costly
than the product developed by the Company. These potential competitors may be
more successful than the Company in manufacturing and marketing their products
and may be able to take advantage of the significant time and effort invested
by the Company to gain medical acceptance of cerebral oximetry. In addition,
two patents issued to an unaffiliated third party and relating to cerebral
oximetry will expire this year, making that technology generally available and
potentially helping the development of competing products. See "Market
Overview."

     The Company also competes indirectly with the numerous companies that sell
various types of medical equipment to hospitals for the limited amount of
funding allocated to capital equipment in hospital budgets. The market for
medical equipment is subject to rapid change due to an increasingly
competitive, cost-conscious environment and to government programs intended to
reduce the cost of medical care. Many of these manufacturers of medical
equipment are large, well-established companies whose resources, reputations
and ability to leverage existing customer relationships may give them a
competitive advantage over the Company. The Company's product and technology
also compete indirectly with many other methods currently used to measure blood
oxygen levels or the effects of low blood oxygen levels.

     The Company believes that a manufacturer's reputation for producing
accurate, reliable and technically advanced products, references from users,
features (speed, safety, ease of use, patient convenience and range of
applicability), product effectiveness and price are the principal competitive
factors in the medical equipment industry.

PROPRIETARY RIGHTS INFORMATION

     The Company has thirteen United States patents and fourteen corresponding
patents in various foreign countries. The Company's patents basically cover
methods and apparatus for introducing light into a body part and receiving,
measuring and analyzing the resulting light and its interaction with tissue.
Such methods also involve receiving, measuring and analyzing the light
transmissivity of various body parts of a single subject, as well as of body
parts of different subjects which provides a standard against which a single
subject can be compared. Although the Company believes that one or more of its
issued patents cover some of the underlying technology used in the Cerebral
Oximeter, only eight of the issued patents expressly refer to examination of
the brain or developments involving the Cerebral Oximeter.

     The Company's initial United States patent, covering the in vivo tissue
examination technology developed in conjunction with the INVOS 2100 and its
predecessor, the SOMA 100, was allowed and issued in 1986 and will expire on
October 14, 2003. The corresponding Canadian patent was issued in 1987, the
corresponding European Community patent was issued in 1990 with related patents
issued in the ten Western European countries which were then member states, and
the corresponding Japanese patent was issued in 1991. The Company's twelve
additional United States patents expire on various dates from February 2005 to
December 2014. The Company also has two patent applications pending in the
United States and several pending patent applications filed in various foreign
countries, with respect to other aspects of its technology relating to the
interaction of light with tissue.

                                       10



<PAGE>   12



     Notwithstanding the Company's patents as noted above, many other patents
have previously been issued to third parties involving optical spectroscopy and
the interaction of light with tissue, some of which relate to the use of
optical spectroscopy in the area of brain metabolism monitoring, the primary
use of the Cerebral Oximeter. No patent infringement claims have been asserted
against the Company.

     In addition to its patent rights, the Company has obtained United States
Trademark registrations for its trademarks "SOMANETICS," "SOMAGRAM," "INVOS,"
"SOMASENSOR" and "WINDOW TO THE BRAIN," and has also obtained registrations of
its basic mark, "SOMANETICS," in thirteen foreign countries.

     The Company also relies on trade secret, copyright and other laws and on
confidentiality agreements to protect its technology, but believes that neither
its patents nor other legal rights will necessarily prevent third parties from
developing or from using similar or related technology to compete against the
Company's product. Moreover, the Company's technology primarily represents
improvements or adaptations of known optical spectroscopy technology, which
might be duplicated or discovered through its patents, reverse engineering or
both.

GOVERNMENT REGULATION

     The testing, manufacture and sale of the Company's products are subject to
regulation by numerous governmental authorities, principally the FDA and
corresponding state and foreign agencies. Pursuant to the Federal Food, Drug,
and Cosmetic Act, and the regulations promulgated thereunder, the FDA regulates
the preclinical and clinical testing, manufacture, labeling, distribution and
promotion of medical devices. Noncompliance with applicable requirements can
result in, among other things, fines, injunctions, civil penalties, recall or
seizure of products, total or partial suspension of production, failure of the
government to grant premarket clearance or premarket approval for devices,
withdrawal of marketing clearances or approvals and criminal prosecution.

     A medical device may be marketed in the United States only with prior
authorization from the FDA unless it is subject to a specific exemption.
Devices classified by the FDA as posing less risk than class III devices are
categorized as class I or II and are eligible to seek "510(k) clearance." Such
clearance generally is granted when submitted information establishes that a
proposed device is "substantially equivalent" in intended use to a class I or
II device already legally on the market or to a "preamendment" class III device
(i.e., one that has been in commercial distribution since before May 28, 1976)
for which the FDA has not called for PMA applications (as defined below). The
FDA in recent years has been requiring a more rigorous demonstration of
substantial equivalence than in the past, including requiring clinical trial
data in some cases. For any devices that are cleared through the 510(k)
process, modifications or enhancements that could significantly affect safety
or effectiveness, or constitute a major change in the intended use of the
device, will require new 510(k) submissions. The Company believes that it now
usually takes from three to six months from the date of submission to obtain
510(k) clearance, but it can take substantially longer. The Cerebral Oximeter
has been categorized as a class II device.

     A device requiring prior marketing authorization that does not qualify for
510(k) clearance is categorized as class III, which is reserved for devices
classified by FDA as posing the greatest risk (e.g., life-sustaining,
life-supporting or implantable devices), or devices that are not substantially
equivalent to a legally marketed class I or class II device. A class III device
generally must receive approval of a premarket approval ("PMA") application,
which requires proving the safety and effectiveness of the device to the FDA.
The process of obtaining PMA approval is expensive and uncertain. The Company
believes that is usually takes from one to three years after filing, but it can
take longer.

     If human clinical trials of a device are required, whether for a 510(k) or
a PMA application, and the device presents a "significant risk," the sponsor of
the trial (usually the manufacturer or the distributor of the device) will have
to file an investigational device exemption ("IDE") application prior to
commencing human clinical trials. The IDE application must be supported by
data, typically including the results of animal and laboratory testing. If the
IDE application is approved by the FDA and one or more appropriate
Institutional Review Boards ("IRBs"), human clinical trials may begin at a
specific number of investigational sites with a specific number of patients, as
approved by the FDA. If the device presents a "nonsignificant risk" to the
patient, a sponsor may begin the clinical trial after obtaining approval for
the study by the IRB at each clinical site without the need for FDA approval.

     In June 1992, the Company received 510(k) clearance from the FDA to market
the Cerebral Oximeter in the United States for use on adults. The Company began
commercial shipments of Cerebral Oximeters and SomaSensors in May 1993. In
November 1993, the Company received notification that the FDA had rescinded the
Company's 510(k) clearance to market the Cerebral Oximeter. As a result, all
commercial sales of the Company's product were suspended. In February 1994, the
Company resumed marketing its product in several foreign countries. In June
1996, the Company received 510(k) clearance from the FDA to market the Cerebral
Oximeter, including the SomaSensor, in the United States.  In October 1997, the
Company obtained FDA clearance for new advances in its INVOS technology that
are incorporated in its next generation Cerebral Oximeter.  The next generation
Cerebral Oximeter was introduced in October 1997 and is expected to be
available in the first quarter of fiscal 1998.

     The Company has made modifications to the Cerebral Oximeter, which the
Company believes do not require the submission of new 510(k) notices. There can
be no assurance, however, that the FDA would agree with any of the Company's
determinations not to submit a new 510(k) notice for any of these changes or
would not require the Company to submit a new 510(k) notice for any of the
changes made to the device. If the FDA requires the Company to submit a new
510(k) notice for any device modification, the Company may be prohibited from
marketing the modified device until the 510(k) notice is cleared by the FDA.

     Any devices manufactured or distributed by the Company pursuant to FDA
clearances or approvals are subject to pervasive and continuing regulation by
the FDA and certain state agencies. Manufacturers of medical devices for
marketing in the United States are required to adhere to applicable regulations
setting forth detailed GMP requirements, which including testing, control and
documentation requirements. Manufacturers must also comply with Medical Device
Reporting requirements that a firm report to the FDA any incident in which its
product may have caused or contributed to a death or serious injury, or in
which its product malfunctioned and, if the malfunction were to recur, it would
be likely to cause or contribute to a death or serious injury. Labeling and
promotional activities are subject to scrutiny by the FDA and, in certain
circumstances, by the Federal Trade Commission. Current FDA enforcement policy
prohibits the marketing of approved medical devices for unapproved uses.

     The Company is subject to routine inspection by the FDA and certain state
agencies for compliance with GMP requirements and other applicable regulations.
The most recent FDA GMP inspection occurred in May 1997.  The FDA finalized
changes to the GMP regulations in 1997, which has increased the cost of
compliance with GMP requirements. The Company also is subject to numerous
federal, state and local laws relating to such matters as safe working
conditions, manufacturing practices, environmental protection, fire hazard
control and disposal of hazardous or potentially hazardous substances.

     If any of the Company's FDA clearances are denied or rescinded, sales of
the Company's product in the United States would be prohibited during the
period the Company does not have such clearances. In such cases the Company
would consider shipping its product internationally and/or assembling it
overseas if permissible and if the Company determines its product to be ready
for commercial shipment. The FDA's current policy is that a medical device that
is not in commercial distribution in the United States, but which needs 510(k)
clearance to be commercially distributed in the United States, can be exported
without the submission of an export request and prior FDA clearance provided
that (i) a company believes the device can be found to be substantially
equivalent through a 510(k) submission, (ii) the device is labeled and intended
for export only, (iii) the device is in accord with the specifications of the
foreign purchaser and (iv) other conditions of the export provisions of the
Food, Drug and Cosmetic Act have been met.

     Congress recently enacted the FDA Modernization Act of 1997.  This law is
intended to make the regulatory process more consistent and efficient.  It is
too early to determine whether, or how, these new requirements will affect the
Company.

SEASONALITY

     The Company's business is seasonal.  The Company's third quarter sales
have typically been lower, compared to other fiscal quarters, principally
because the fiscal quarter coincides with the summer vacation season,
especially in Europe, the United States and Japan.

INSURANCE

     Because the Cerebral Oximeter is intended to be used in hospital critical
care units with patients who may be seriously ill or may be undergoing
dangerous procedures, the Company may be exposed to serious potential product
liability claims. The Company has obtained products liability insurance with a
liability limit of $2,000,000. The Company also maintains coverage for property

directors' and officers' liability and workers' compensation. The Company does

EMPLOYEES

     As of January 9, 1998, the Company employed 41 full-time individuals,
including 22 in sales and marketing, five in research and development, eight in
general and administration and six in manufacturing, quality and service. The
Company also uses three consultants. The Company believes that its future
success is dependent, in large part, on its ability to attract and retain
highly qualified managerial, marketing and technical personnel. The Company's
employees are not represented by a union or subject to a collective bargaining
agreement. The Company believes that its relations with its current employees
are good.

FINANCIAL INFORMATION ABOUT FOREIGN AND DOMESTIC OPERATIONS AND EXPORT SALES

     The Company is located in Troy, Michigan and has no other locations.  The
Company's export sales for the fiscal years ended November 30, 1997, 1996 and

ITEM 2. PROPERTIES

     The Company leases 23,392 square feet of office, manufacturing and
warehouse space in Troy, Michigan, of which approximately 12,000 square feet is
office space for sales and marketing, engineering, accounting and other
administrative activities. The lease agreement was extended in fiscal 1997,
with the extension commencing January 1, 1998 and expiring December 31, 1999.
The extension also provides the Company with an option to extend for another
year under the same terms and conditions.  The minimum monthly lease payment
for the extended term is approximately $14,700, excluding other occupancy
costs. The Company believes that, depending on sales of the Cerebral Oximeter,
its current facility is more than suitable and adequate for its current needs,
including assembly of the Cerebral Oximeter by the Company and conducting
Company operations in compliance with prescribed FDA/GMP guidelines and will
allow for substantial expansion of the Company's business and number of
employees. The Company has subleased a portion of its warehouse space on a
month-to-month basis for $2,700 per month.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
        RESULTS OF OPERATIONS

        The following Management's Discussion and Analysis of Financial 
Condition and Results of Operations includes forward-looking statements
with respect to the Company's future financial performance.  These
forward-looking statements are subject to various risks and uncertainties,
including the factors described under the caption "Risk Factors" and elsewhere
in the Company's Registration Statement on Form S-1 (file no. 333-25275)
effective May 30, 1997 and elsewhere in this Report, that could cause actual
results to differ materially from historical results or those currently
anticipated.

RESULTS OF OPERATIONS

OVERVIEW

     Somanetics Corporation develops, manufactures and markets the INVOS
Cerebral Oximeter, the only FDA-cleared, non-invasive patient monitoring system
that continuously measures changes in the blood oxygen level in the adult
brain.  In 1988, the Company began clinical studies of the Cerebral Oximeter on
human patients. In June 1992, the Company received 510(k) clearance from the
FDA to market the Cerebral Oximeter in the United States for use on adults. The
Company began commercial shipments of Cerebral Oximeters and SomaSensors in May
1993. In November 1993, the FDA rescinded the Company's clearance to market the
Cerebral Oximeter and the related disposable SomaSensor in the United States,
and the Company suspended all commercial sales. In February 1994, the Company
resumed marketing its product in several foreign countries, and in June 1996
the Company received clearance from the FDA to market the Cerebral Oximeter and
the related disposable SomaSensor in the United States. In October 1997, the
Company obtained FDA clearance for new advances in its INVOS technology that
are incorporated in its next generation Cerebral Oximeter.  The next generation
4100 Cerebral Oximeter was introduced in October 1997 and is expected to be
available in the first quarter of fiscal 1998.

     The Company recently emerged from the development stage and has an
accumulated deficit of $36,366,536 through November 30, 1997.  From its
inception in January 1982 through November 30, 1997, its primary activities
have consisted of research and development of the INVOS technology, a
discontinued product, the Cerebral Oximeter and the related disposable
SomaSensor. The Company believes that its accumulated deficit will continue to
increase for the foreseeable future.

     The Company derives its revenues from sales of Cerebral Oximeters and
SomaSensors to its distributors and, since the June 1996 FDA clearance, to
hospitals in the U.S. through its direct sales employees. The Company
recognizes revenues when it ships its product to its distributors or to
hospitals. Payment terms are generally net 30 days for United States sales and
net 60 days or longer for international sales. The Company's primary expenses,
excluding the cost of its product, are selling, general and administrative and
research, development and engineering, which are generally expensed as
incurred. The Company capitalizes its patent costs and amortizes them over 17
years. Since May 1994, the Company has exchanged the new model 3100A Cerebral
Oximeters for its model 3100 Cerebral Oximeters. The Company refurbishes the
model 3100 Cerebral Oximeters it receives and sells them approximately at cost
in countries that do not require compliance with the standards met by the model
3100A. Such sales reduce the Company's overall gross margin. When the Company's
next generation Cerebral Oximeter is introduced into the marketplace, the
Company expects to upgrade existing model 3100A Cerebral Oximeters.  The next
generation Cerebral Oximeter is expected to be available in the first quarter
of fiscal 1998.

FISCAL YEAR ENDED NOVEMBER 30, 1997 COMPARED TO FISCAL YEAR ENDED NOVEMBER 30,
1996

     Net revenues increased approximately $434,000, or 56%, from $778,200 in
the fiscal year ended November 30, 1996 to $1,211,784 in the fiscal year ended
November 30, 1997. The increase in sales was primarily attributable to an
increase in United States sales for fiscal 1997 of approximately $490,000, from
approximately $33,000 in fiscal 1996 to approximately $523,000 in fiscal 1997.
The sales increase was partially offset by a $56,000 decrease in international
sales in fiscal 1997 compared to fiscal 1996, primarily due to reduced
shipments to Baxter Limited in Japan, which is delaying purchases until
shipment of the next generation Cerebral Oximeter is permitted in Japan, and a
21% decrease in the average selling price of Cerebral Oximeters in fiscal 1997
compared to fiscal 1996 primarily as a result of lower international prices for
the Cerebral Oximeter, partially offset by increased prices realized by the

                                       19



<PAGE>   21

Company as a result in a change in the mix between sales directly to hospitals
and sales through distributors.  Approximately 57% of the Company's net
revenues in fiscal 1997 were export sales, as compared to approximately 96% in
fiscal 1996.  Sales of model 3100A Cerebral Oximeters, SomaSensors, and
refurbished model 3100 Cerebral Oximeters comprised approximately 60%, 30% and
10%, respectively, of the Company's fiscal year 1997 net revenues, and 63%, 23%
and 14%, respectively, of the Company's fiscal year 1996 net revenues.  Two
international distributors and one domestic distributor accounted for
approximately 28%, 11%,  and 12%, respectively, of net revenues for fiscal year
1997, and two international distributors accounted for approximately 62% and
15%, respectively, of net revenues for fiscal year 1996. First quarter fiscal
1998 sales are expected to be depressed until the Company's next generation
Cerebral Oximeter is available because some existing and prospective customers
are deferring their decisions about whether to purchase the current product
until the new Cerebral Oximeter is available.

     Gross margin as a percentage of net revenues for the fiscal years ended
November 30, 1997 and 1996 were approximately 48% and 51%, respectively. Gross
margin as a percentage of net revenues decreased in fiscal 1997 from fiscal
1996 primarily because the Company realized lower average selling prices for
model 3100A Cerebral Oximeters in fiscal 1997, the cost to the Company of the
SomaSensor was higher in fiscal 1997, and SomaSensors were a larger portion of
overall sales.  This decrease was partially offset by the decrease in the
portion of net revenues attributable to refurbished model 3100 Cerebral
Oximeters in fiscal 1997.

     The Company's research, development and engineering expenses increased
approximately $501,000, or 213%, from $235,354 for the fiscal year ended
November 30, 1996 to $736,427 for the fiscal year ended November 30, 1997. The
increase in fiscal 1997 is primarily attributable to increased costs of
development materials and consulting fees in connection with new product
development, principally the next generation adult Cerebral Oximeter, increased
clinical testing, and an increase in research, development, and engineering
personnel from two employees at November 30, 1996 to five employees at November
30, 1997.

     Selling, general and administrative expenses increased approximately
$2,688,000, or 76%, from $3,549,939 for the fiscal year ended November 30, 1996
to $6,238,330 for the fiscal year ended November 30, 1997. The increase for
fiscal 1997 is primarily attributable to (i) a $1,539,000 increase in salaries,
wages, incentive compensation and related expenses as a result of the
additional personnel hired during fiscal 1997 (from 30 employees as of November
30, 1996, eight of which were hired during the fourth quarter of fiscal 1996,
to 40 employees as of November 30, 1997, most of whom were on the payroll for
the entire fiscal 1997), (ii) a $446,000 increase in selling-related expenses
primarily as a result of increased expenses for employee travel, medical
affairs, marketing, clinical research, and sales demonstration equipment use,
and industry trade shows and advertising, (iii) a $280,000 increase in
miscellaneous expense primarily related to inventory obsolescence reserves
recorded during the third and fourth quarters of fiscal 1997, (iv) a $152,000
increase in bad debts expense, and (v) a $276,000 increase in other personnel
and office-related expenses, including temporary services, telephone,
recruiting and training, and office supplies.

FISCAL YEAR ENDED NOVEMBER 30, 1996 COMPARED TO FISCAL YEAR ENDED NOVEMBER 30,
1995

     Net revenues decreased approximately $558,000, or 42%, from $1,335,970 in
the fiscal year ended November 30, 1995 to $778,200 in the fiscal year ended
November 30, 1996. The decrease in sales was primarily attributable to a more
than 20% decrease in the average selling price of model 3100A Cerebral
Oximeters to distributors and reduced shipments to Europe and to Baxter Limited
in Japan. Approximately 96% and 100% of the Company's net revenues in fiscal
1996 and 1995, respectively, were export sales. Sales of refurbished model 3100
Cerebral Oximeters, model 3100A Cerebral Oximeters and SomaSensors comprised
approximately 14%, 63% and 23%, respectively, of the Company's fiscal year 1996
net revenues, and 10%, 74% and 16%, respectively, of the Company's fiscal year
1995 net revenues.

     Two international distributors accounted for approximately 62% and 15%,
respectively, of net revenues for fiscal year 1996, and approximately 53% and
13%, respectively, of net revenues for fiscal year 1995. The Company terminated
its Japanese distributor effective January 28, 1995. In March 1995, the Company
announced the engagement of Baxter Limited as its exclusive distributor in
Japan. In April 1995, the Company received its license from the Japanese
Ministry of Health and Welfare to market its product in Japan.

     Gross margin as a percentage of net revenues for the fiscal years ended
November 30, 1996 and 1995 were approximately 51% and 51%, respectively. Gross
margin as a percentage of net revenues decreased in fiscal 1996 from fiscal
1995 primarily because 14% of net revenues in fiscal 1996 consisted of sales of
refurbished model 3100 Cerebral Oximeters, and because of lower average selling
prices for model 3100A Cerebral Oximeters and an increase in the cost of the
SomaSensor, partially offset by an approximately 10% decrease in materials cost
for the Cerebral Oximeter in fiscal 1996.

     The Company's research, development and engineering expenses decreased
approximately $51,000, or 18%, from $285,893 for the fiscal year ended November
30, 1995 to $235,354 for the fiscal year ended November 30, 1996. The decrease
in fiscal 1996 is primarily attributable to an approximately $70,000 charge in
fiscal 1995 to engineering expenses for obsolete purchased parts inventory
relating to engineering design changes to the model 3100A Cerebral Oximeter,
partially offset by increased consulting fees in fiscal 1996 in connection with
new product development since the Company received 510(k) clearance for the
Cerebral Oximeter.

     Selling, general and administrative expenses increased approximately
$247,000, or 7%, from $3,302,751 for the fiscal year ended November 30, 1995 to
$3,549,939 for the fiscal year ended November 30, 1996. The increase for fiscal
1996 is primarily attributable to (i) a $217,000 increase in selling-related
expenses, primarily due to the costs of providing Cerebral Oximeters for
clinical research and to United States sales personnel and the added cost of
promotional equipment and materials in the United States, partially offset by a
decrease in travel and related expenses and two fewer sales and marketing
employees for approximately seven months of the fiscal year, (ii) one-time
charges of $175,000 for write-downs of excess refurbished model 3100 Cerebral
Oximeters and obsolete inventory, (iii) an increase in nonproductive, indirect
labor and overhead of $197,000 and (iv) a $71,000 increase in warranty
expenses, partially offset by (a) a decrease of $237,000 in salaries and wages,
primarily due to a reduction in payroll and related benefits, partially offset
by an increase in temporary and contract labor and an increase in consulting
services, (b) a $134,000 decrease in occupancy costs principally due to the
reduction in personnel and the expiration of operating leases and (c) a
decrease in depreciation and amortization expenses of $67,000.

     The $121,500 bad debt recovery (resulting from the returns of INVOS 3100
Cerebral Oximeters by United States distributors whose receivables had been
written off), $57,200 reversal of the reserve for the extra cost of exchanging
new INVOS 3100A Cerebral Oximeters for INVOS 3100 Cerebral Oximeters held by
United States distributors who had not yet paid for their Cerebral Oximeters,
and the cost of upgrading model 3100 Cerebral Oximeters, and $27,600 reversal
of the reserve for replacing SomaSensors recalled in 1993, were partially
offset by a $150,000 reserve accrued for excess INVOS 3100 Cerebral Oximeters
in inventory and obsolete inventory and a $46,000 reserve for doubtful accounts
taken in connection with receivables from some foreign distributors. These
amounts are included in selling, general and administrative expenses for fiscal
1996.

EFFECTS OF INFLATION

     The Company does not believe that inflation has had a significant impact
on its financial position or results of operations in the past three years.

LIQUIDITY AND CAPITAL RESOURCES

     Net cash used in operations during fiscal 1997 was approximately
$5,436,000. Cash was used primarily to fund the Company's net loss, including
selling, general and administrative expenses and research, development and
engineering expenses (approximately $6,105,000, net of depreciation and
amortization expense).  This primary use of cash was partially offset by a
decrease in net inventory (approximately $498,000) due to management's decision
to lower inventory levels of INVOS 3100A Cerebral Oximeters and its components
to prepare for the introduction of the next generation Cerebral Oximeter and
increased inventory obsolescence recorded in the third and fourth quarters of
fiscal 1997 in anticipation of the new product launch, and an increase in
accrued liabilities (approximately $144,000) as of the end of fiscal 1997.
Accounts receivable increased only $262.  Higher sales were substantially
offset by increased allowances for doubtful accounts.  Accounts payable
increased $26,462.  The Company used some of the proceeds of its public
offering of Common Shares on June 4, 1997, to pay previously delayed balances
due vendors; however, as of November 30, 1997 payables were increasing due to
inventory purchases related to the beginning of production of the Company's
next generation Cerebral Oximeter.  Management expects to

                                       21



<PAGE>   23

build inventory levels of the next generation Cerebral Oximeter and its
components in the first quarter of fiscal 1998.  Management also expects
working capital requirements to increase if sales increase.

     Capital expenditures in fiscal 1997 were approximately $244,000, primarily
for tooling to manufacture the next generation Cerebral Oximeter.

     The Company's principal sources of operating funds have been the proceeds
of equity investments from sales of the Company's Common Shares.  See
Statements of Shareholders' Equity of the Company's Financial Statements
included in Item 8 of this Report.  On June 4, 1997, the Company completed the
public offering of 2,000,000 newly-issued Common Shares, at a price of $4.00
per share, for gross proceeds of $8,000,000, through an offering underwritten
by Brean Murray & Co., Inc.  The net proceeds to the Company, after deducting
the underwriting discount and the expenses of the offering, were approximately
$7,000,000.  The Company also granted the underwriter warrants to purchase
200,000 Common Shares at $4.80 per share exercisable during the four-year
period beginning May 30, 1998.

     As of November 30, 1997 the Company had working capital of $4,510,973,
cash, cash equivalents and marketable securities of $4,603,156, total current
liabilities of $788,476 and shareholders' equity of $4,888,956.  The Company
has no loan commitments.

     The Company expects that its primary needs for liquidity in fiscal 1998
will be (i) to fund its losses and sustain its operations, including funding
(a) marketing costs for the Cerebral Oximeter; (b) additional sales and
marketing, manufacturing, service, quality control and medical affairs
personnel expected to be hired in fiscal 1998; (c) further development and
testing of enhancements to, and product extensions of, the Cerebral Oximeter;
and (d) additional research and development projects and (ii) for working
capital, including increased accounts receivable and inventories of components
and sales units to satisfy expected sales orders. In addition, management has
budgeted approximately $370,000 for capital expenditures during fiscal 1998,
primarily for demonstration units of its next generation Cerebral Oximeter.

     The Company believes that cash, cash equivalents and marketable securities
on hand at November 30, 1997 will be sufficient to sustain the Company's
operations at budgeted levels and its need for liquidity into the second half
of fiscal 1998.  By that time the Company will be required to raise additional
cash either through additional sales of its product, through sales of
securities, by incurring indebtedness or by some combination of the foregoing.
If the Company is unable to raise additional cash by that time, it will be
required to reduce or discontinue its operations.

     The estimated length of time current cash, cash equivalents and marketable
securities will sustain the Company's operations is based on certain estimates
and assumptions made by the Company.  Such estimates and assumptions are
subject to change as a result of actual experience.  There can be no assurance
that actual capital requirements necessary to market the Cerebral Oximeter and
SomaSensor, to develop enhancements to, and product extensions of, the Cerebral
Oximeter, to conduct research and development concerning additional potential
applications of the Company's technology and for working capital will not be
substantially greater than current estimates.

     The Company does not believe that product sales will be sufficient to fund
the Company's operations in fiscal 1998.

     The Company is negotiating with an underwriter to underwrite a proposed
public offering, or to act as a placement agent for a private placement, by the
Company of newly-issued securities.  The offerings may be subject to
shareholder approval of an amendment to the Company's Articles of Incorporation
increasing the authorized Common Shares to 20,000,000 (the "Amendment").  Among
other things, the offering will be contingent on satisfactory completion of a
due diligence investigation of the Company by the underwriter, any private
placement investor and their agents.  Any such public offering will be made only
by means of a prospectus.  In addition, the type and amount of security, if
any, that might ultimately be issued in any such offering have not yet been
definitively determined and will be dependent on negotiations with the
underwriter, any private placement investor, market conditions and management's
then current estimate of the proceeds necessary or desired to sustain the
Company's operations.  There can be no assurance that such offering will occur
or that the Company will be able to raise any capital or capital in amounts it
desires, or on terms and conditions acceptable to the Company.

                                       22



<PAGE>   24


     Also, as of November 30, 1997, there were 60,400 redeemable warrants
outstanding, exercisable at $20.00 per share until July 13, 2000, and 55,120
redeemable warrants outstanding exercisable at $17.50 per share until April 1,
2001. These warrants were issued in the Company's 1995 and April 1996
Regulation S securities offerings. The conditions permitting the Company to
redeem these warrants have not been met as of January 9, 1998. In addition, the
placement agents and their transferees hold warrants to purchase 64,394 Common
Shares exercisable at $12.50 per share and 15,000 warrants exercisable at
$14.40 per share.  Also, as described above, the underwriter of the 1997 public
offering received warrants to purchase 200,000 Common Shares exercisable at
$4.80 per share.  It is unlikely that these warrants will be exercised if the
exercise price exceeds the market price of the Common Shares.  The Company has
the right to reduce the exercise price of these warrants.

     The Company has no loan commitments.

     There can be no assurance that even if the Company receives additional
capital, it will be able to achieve the level of sales necessary to sustain its
operations.  There can be no assurance that the Company will be able to obtain
any funds on terms acceptable to the Company and at times required by the
Company through sales of the Company's product, sales of securities or loans in
sufficient quantities. The report of the Company's Independent Auditors
contains an explanatory paragraph relating to the uncertainty concerning the
Company's ability to continue as a going concern.  See "Independent Auditors
Report" accompanying the Financial Statements in Item 8 of this Report.

     The Company's ability to use its accumulated net operating loss
carryforwards to offset future income, if any, for income tax purposes, is
limited due to the initial public offering of its securities in March 1991. See
Note 6 of Notes to Financial Statements included in Item 8 of this Report.

     YEAR 2000 COMPLIANCE

     The Company does not expect the cost of converting its computer systems to
year 2000 compliance will be material to its financial condition or results of
operations.  The Company believes that it will be able to achieve year 2000
compliance by the end of 1999, and does not currently anticipate any disruption
in its operations as the result of any failure by the Company to be in
compliance.  The Company does not currently have any information concerning the
year 2000 compliance status of its suppliers and customers.

     NEW ACCOUNTING PRONOUNCEMENTS

     In March 1997, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") No. 128, "Earnings per
Share." This Statement establishes standards for computing and presenting
earnings per share ("EPS") and applies to all entities with publicly-held
common shares or potential common shares. This Statement replaces the
presentation of primary EPS and fully-diluted EPS with a presentation of basic
EPS and diluted EPS, respectively. Basic EPS excludes dilution and is computed
by dividing earnings available to common shareholders by the weighted-average
number of common shares outstanding for the period. Similar to fully diluted
EPS, diluted EPS reflects the potential dilution of securities that could share
in the earnings. This Statement is not expected to have a material effect on
the Company's reported EPS amounts. The Statement is effective for the
Company's financial statements for the quarter ending February 28, 1998.

     In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive
Income," which is effective for fiscal years beginning after December 15, 1997.
This Statement establishes standards for reporting and display of
comprehensive income and its components in financial statements. The Statement
is effective for the Company's financial statements for the year ending
November 30, 1999.

     In June 1997, the FASB issued SFAS No. 131, "Disclosures about Segments of
an Enterprise and Related Information,"  which is effective for fiscal years
beginning after December 15, 1997.  This statement establishes standards for
the way a public business enterprise reports certain information about
operating segments, and discloses enterprise-wide information about the 
company's products and services, activities in different geographic areas, and 
the company's reliance on major customers.  The statement is effective for the
Company's financial statements for the year ending November 30, 1999.

ITEM 8.   FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA



Independent Auditors' Report


To the Board of Directors and Shareholders of
Somanetics Corporation
Troy, Michigan


We have audited the accompanying balance sheets of Somanetics Corporation (the
"Company") as of November 30, 1997 and 1996, and the related statements of
operations, shareholders' equity, and cash flows for each of the three years in
the period ended November 30, 1997.  Our audits also included the financial
statement schedule listed in the index at Item 14.  These financial statements
and the financial statement schedule are the responsibility of the Company's
management.  Our responsibility is to express an opinion on these financial
statements and the financial statement schedule based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement.  An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements.  An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation.  We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, such financial statements present fairly, in all material
respects, the financial position of the Company at November 30, 1997 and 1996,
and the results of its operations and its cash flows for each of the three
years in the period ended November 30, 1997 in conformity with generally
accepted accounting principles.  Also, in our opinion, such financial statement
schedule, when considered in relation to the basic financial statements taken
as a whole, presents fairly in all material respects the information set forth
therein.

The accompanying financial statements have been prepared assuming that the
Company will continue as a going concern.  As discussed in Note 2 to the
financial statements, conditions exist which raise substantial doubt about the
Company's ability to continue as a going concern.  Management's plans
concerning these matters are also described in Note 2.  The financial
statements do not include any adjustments that might result from the outcome of
these uncertainties.

The Company was in the development stage at November 30, 1996; during the year
ended November 30, 1997, the Company completed its development activities and
commenced its planned principal operations.

1.  Organization and Operations

     Somanetics Corporation (the "Company"), a Michigan corporation formed in
January 1982, develops, manufactures and markets the INVOS Cerebral Oximeter
(the "Cerebral Oximeter"), the only FDEA-cleared, noninvasive patient monitoring
system that continuously measures changes in the blood oxygen level in the adult
brain.  The Cerebral Oximeter is based on the Company's proprietary in vivo
Optical Spectroscopy ("INVOS") technology.  INVOS analyzes various
characteristics of human blood and tissue by measuring and analyzing low
intensity visible and near-infrared light transmitted into portions of the 
body. The Company has incurred research, product development and other expenses
invloved in designing, developing, marketing and selling its product, as well as
devoting efforts to raising capital.

     The Company was in the development stage at November 30, 1996; during
the year ended November 30, 1997 the Company completed its devdelopment
activites and commenced its planned principal operations.

2.  Financial Statement Presentation

     The Company has not achieved sales necessary to support operations. The
Company has incurred an accumulated deficit of $36,366,536 through November 30,
1997. The Company had working capital of $4,510,973, cash, cash equivalents and
marketable securities of $4,603,156, total current liabilities of $788,476 and
shareholders' equity of $4,888,956, as of November 30, 1997.

     On June 6, 1996 and October 13, 1997 the Company received clearance from
the FDA to market its model 3100A adult Cerebral Oximeter and enhancements to
its Cerebral Oximeter, respectively, in the United States.  The Company's
current financial condition and results of operations and the status of its
product marketing efforts and sales have been affected by the process of
obtaining such clearances.

     As of January 9, 1998, the Company had 25 international distributors, 7
United States distributors (including Puerto Rico), 19 direct sales personnel
and 1 international sales consultant. During fiscal 1997, the Company sold its
product to 13 of its international distributors and all of its United States
distributors, and devoted most of its marketing to introducing cerebral
oximetry patient monitoring into the operating rooms of hospitals.  There can
be no assurance that the Company will be successful or profitable in marketing
the Cerebral Oximeter and the related SomaSensor.

     Management believes that markets exist for the product the Company has
developed; however, there is an inherent uncertainty associated with the
success of such product. The likelihood of success of the Company must be
considered in view of the Company's limited resources and current financial
condition, the problems and expenses frequently encountered in connection with
formation of a new business, the ability to raise new funds, the development
and application of new technology and the competitive environment in which the
Company operates.

     The net proceeds from the sales of Common Shares in the Regulation S
offering in November 1996 (Note 3) and the net proceeds from the public
offering of Common Shares in June 1997 (Note 3) were sufficient to fund the
Company's working capital requirements for the fiscal year ended November 30,
1997. Current sales are not sufficient to fund operations.  During fiscal 1997,
the Company received approximately $7.0 million in net proceeds from the sale
of Common Shares in a public offering registered under the Securities Act of
1933 (Note 3).

                         NOTES TO FINANCIAL STATEMENTS


     The Company believes that the cash, cash equivalents and marketable
securities on hand at November 30, 1997 will be sufficient to sustain the
Company's operations at budgeted levels and its needs for liquidity into the
second half of fiscal 1998.  By that time the Company will be required to raise
additional cash either through additional sales of its product, through sales
of securities, by incurring indebtedness or by some combination of the
foregoing. If the Company is unable to raise additional cash by that time, it
will be required to reduce or discontinue its operations.

     The estimated length of time current cash, cash equivalents and marketable
securities will sustain the Company's operations is based on certain estimates
and assumptions made by the Company. Such estimates and assumptions are subject
to change as a result of actual experience. There can be no assurance that
actual capital requirements necessary to market the Cerebral Oximeter and
SomaSensor, to develop enhancements to, and product extensions of, the Cerebral
Oximeter, to conduct research and development concerning additional potential
applications of the Company's technology and for working capital will not be
substantially greater than current estimates.

     The Company does not believe that product sales will be sufficient to fund
the Company's operations in fiscal 1998.

     See Note 11 for discussion of negotiations with an underwriter for sales
of securities.

  The Company has no loan commitments.

     There can be no assurance that even if the Company receives additional
capital, it will be able to achieve the level of sales necessary to sustain its
operations. There can be no assurance that the Company will obtain any funds on
terms acceptable to the Company and at times required by the Company through
sales of the Company's product, sales of securities or loans in sufficient
quantities.

     These factors, among others, raise substantial doubt about the Company's
ability to continue as a going concern. The financial statements do not include
any adjustments relating to the recoverability and classification of asset
carrying amounts or the amount and classification of liabilities that might be
necessary should the Company be unable to continue as a going concern.


3. STOCK OFFERINGS AND COMMON SHARES

     On July 14, 1995 the Company completed the placement of 75,000 Units, at a
price of $25.00 per Unit, for gross proceeds of $1,875,000, through an offering
complying with Regulation S under the Securities Act of 1933, (the "Act"). The
net proceeds to the Company, after deducting the placement agents' fee and the
expenses of the offering, were approximately $1,593,000. Each Unit consisted of
two newly-issued Common Shares, par value $.01 per share, and one warrant to
purchase one Common Share.

     The Warrants are immediately exercisable and transferable separately from
the Common Shares. Each Warrant entitles the holder to purchase one Common
Share at an initial exercise price of $20.00 per share, subject to adjustment,
at any time through July 13, 2000, unless earlier redeemed. The Warrants are
redeemable for $.10 by the Company at any time after January 13, 1996, if
certain conditions are met; these conditions had not been met as of January 9,
1998.

     The Company also granted the placement agent warrants to purchase 15,000
Common Shares at $14.375 per share exercisable during the four-year period
beginning July 14, 1996.

                         NOTES TO FINANCIAL STATEMENTS


     On April 2, 1996, the Company completed the placement of 57,120 Units, at
a price of $25.00 per Unit, for gross proceeds of $1,428,000, through an
offering complying with Regulation S under the Act. The net proceeds to the
Company, after deducting the placement agents' fee and the expenses of the
offering, were approximately $1,284,000. Each Unit consists of two newly-issued
Common Shares, par value $.01 per share, and one warrant to purchase one Common
Share.

     The Warrants are immediately exercisable and transferable separately from
the Common Shares. Each Warrant entitles the holder to purchase one Common
Share at an initial exercise price of $17.50 per share, subject to adjustment,
at any time through April 1, 2001, unless earlier redeemed. The Warrants are
redeemable for $.10 by the Company at any time if certain conditions are met;
these conditions have not been met as of January 9, 1998.

     The Company also granted the placement agent warrants to purchase 11,424
Common Shares at $12.50 per share exercisable during the four-year period
beginning April 2, 1997.

     Pursuant to an amended agreement with Rauscher Pierce & Clark, Inc. and
Rauscher Pierce & Clark Limited (collectively, the "Placement Agent") in
connection with the April 2, 1996 Regulation S offering, the Company agreed to
permit a person designated by the Placement Agent to attend meetings of the
Company's Board of Directors until the 1998 Annual Meeting of Shareholders and
to participate in discussions at such meetings.

     Also, on November 21, 1996, the Company completed the placement of 366,841
newly-issued Common Shares at a price of $11.50 per share through an offering
complying with Regulation S under the Act. The net proceeds to the Company were
approximately $3,568,000.

     During fiscal 1996, 14,600 warrants issued in the Company's 1995
Regulation S Offering and exercisable at $20.00 per share, and 2,000 warrants
issued in the Company's April 1996 Regulation S Offering and exercisable at
$17.50 per share, were exercised, and the Company paid the placement agent in
such offerings a $16,350 fee in connection with those exercises. As of November
30, 1997, there were 60,400 redeemable warrants outstanding exercisable at
$20.00 per share until July 13, 2000 and 55,120 redeemable warrants outstanding
exercisable at $17.50 per share until April 1, 2001. These warrants were issued
in the Company's 1995 and April 1996 Regulation S Offerings. The conditions
permitting the Company to redeem these warrants have not been met as of January
9, 1998. In addition, the Placement Agent and their transferees hold warrants
to purchase 52,970 Common Shares exercisable at $12.50 per share, 15,000 Common
Shares exercisable at $14.40 per share and 11,424 Common Shares exercisable at
$12.50 per share. There can be no assurance that additional warrants will be
exercised and it is unlikely that they will be exercised if the exercise price
exceeds the market price of the Common Shares. The Company has the right to
reduce the exercise price of these warrants.

     On January 15, 1997, the Company's Board of Directors approved an
amendment and restatement of the Company's Restated Articles of Incorporation
to (i) effect a one-for-ten reverse stock split of the Company's Common Shares
while keeping 6,000,000 authorized Common Shares, at a par value of $0.01, and
(ii) remove provisions relating to the Convertible Preferred Shares redeemed
February 28, 1996, all subject to shareholder approval at the 1997 Annual
Meeting of Shareholders.  The Company's shareholders approved such amendment
and restatement at the 1997 Annual Meeting of Shareholders on March 25, 1997,
and the reverse stock split became effective on April 10, 1997.  All
information contained in these financial statements gives retroactive effect to
the 1-for-10 reverse stock split effected April 10, 1997.

     On June 4, 1997, the Company completed the public offering of 2,000,000
newly issued Common Shares at a price of $4.00 per share, for gross proceeds of
$8,000,000, through an offering underwritten by Brean Murray & Co., Inc.  The
net proceeds to the Company, after deducting the underwriting discount and the
estimated expenses of the offering, were approximately $7,000,000.  The Company
also granted the underwriter warrants to purchase 200,000 Common Shares at
$4.80 per share exercisable during the four-year period beginning May 30, 1998.

     Property and Equipment are stated at cost. Depreciation and amortization
are computed using the straight-line method over the estimated useful lives of
the assets, which range from three to five years.

     Patents and Trademarks are recorded at cost and are being amortized on the
straight-line method over 17 years. Accumulated amortization was $39,516 and
$32,604 at November 30, 1997 and 1996, respectively.

     Revenue Recognition occurs upon shipment to customers.

     Research, Development and Engineering costs are expensed as incurred.

     Loss Per Common Share is computed using the weighted average number of
common shares outstanding during each period. Common Shares issuable under
stock options and warrants have not been considered in the computation of the
net loss per Common Share because such inclusion would be antidilutive. On
April 10, 1997, the Company effected a 1-for-10 reverse stock split (Note 3).

                         NOTES TO FINANCIAL STATEMENTS


     Accounting Pronouncements In March 1997, the Financial Accounting
Standards Board ("FASB") issued Statement of Financial Accounting Standards
("SFAS")  No. 128, "Earnings per Share." This Statement establishes standards
for computing and presenting earnings per share ("EPS") and applies to all
entities with publicly-held common shares or potential common shares. This
Statement replaces the presentation of primary EPS and fully-diluted EPS with a
presentation of basic EPS and diluted EPS, respectively. Basic EPS excludes
dilution and is computed by dividing earnings available to common shareholders
by the weighted-average number of common shares outstanding for the period.
Similar to fully diluted EPS, diluted EPS reflects the potential dilution of
securities that could share in the earnings. This Statement is not expected to
have a material effect on the Company's reported EPS amounts. The Statement is
effective for the Company's financial statements for the quarter ending
February 28, 1998.

     In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive
Income," which is effective for fiscal years beginning after December 15, 1997.
This Statement establishes standards for reporting and display of
comprehensive income and its components in financial statements. The Statement
is effective for the Company's financial statements for the year ending
November 30, 1999.

     In June 1997, the FASB issued SFAS No. 131, "Disclosures about Segments of
an Enterprise and Related Information,"  which is effective for fiscal years
beginning after December 15, 1997.  This statement establishes standards for
the way a public business enterprise reports certain information about
operating segments, and discloses enterprise-wide information about the 
company's products and services, activities in different geographic areas, and 
the company's reliance on major customers.  The statement is effective for the
Company's financial statements for the year ending November 30, 1999.

     Use Of Estimates The preparation of financial statements in conformity
with generally accepted accounting principles requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities, the disclosure of contingent assets and liabilities, and the
reported amounts of revenues and expenses for each fiscal period. Actual
results could differ from those estimated.


5. ACCRUED LIABILITIES

  Accrued liabilities consist of the following:

6. INCOME TAX

     Deferred income taxes reflect the estimated future tax effect of (i)
temporary differences between the amount of assets and liabilities for
financial reporting purposes and such amounts as measured by tax laws and
regulations and (ii) net operating loss and tax credit carryforwards. The
Company's deferred tax assets primarily represent the tax benefit of net
operating loss carryforwards and research and general business tax credit
carryforwards. The Company had deferred tax assets of approximately $12,440,000
and $9,124,000 for the years ended November 30, 1997 and 1996, respectively,
which were entirely offset by valuation allowances, due to the uncertainty of
utilizing such assets against future earnings, prior to their expiration. The
components of deferred income tax assets as of November 30, 1997 and 1996 were
as follows:

     As of November 30, 1997, net operating loss carryforwards of approximately
$35.2 million were available for Federal income tax purposes. The Company's
ability to use the net operating loss carryforwards incurred on or before March
27, 1991 (the date the Company completed its initial public offering) is
limited to approximately $296,000 per year. Research and business general tax
credits of $267,000 are also available to offset future taxes. These losses and
credits expire, if unused, at various dates from 1998 through 2012.

     Utilization of the Company's net operating loss carryforwards, tax credit
carryforwards and certain future deductions could be restricted, in the event
of future changes in the Company's equity structure, by provisions contained in
the Tax Reform Act of 1986.


7. COMMITMENTS AND CONTINGENCIES

     On September 10, 1991 the Company entered into a lease agreement for a
23,392 square foot, stand-alone office, assembly and warehouse facility. The
current lease, as amended,  expires December 31, 1999 and grants the Company a
one-year renewal option.

     Operating and building lease expense for the years ended November 30,
1997, 1996 and 1995 was approximately $175,700, $173,500, and $278,000
respectively. Approximate future minimum lease commitments are as follows:

                         NOTES TO FINANCIAL STATEMENTS


     In December 1991, the Company amended and restated its profit sharing plan
to include a 401(k) plan covering substantially all employees. Under provisions
of the plan, participants may contribute, annually, between 1% and 15% of their
compensation. The Company, at the discretion of its Board of Directors, may
contribute matching contributions or make other annual discretionary
contributions to the plan, all of which, together with the participants'
contributions, cannot exceed 15% of the total compensation paid by the Company
to eligible employees. No Company matching or discretionary contributions were
made to the plan for the years ended November 30, 1997, 1996 or 1995.

     On April 25, 1994, a shareholder of the Company filed suit in the United
States District Court for the Eastern District of Michigan, individually and on
behalf of all others similarly situated, against the Company and Gary D. Lewis,
the Company's former Chairman of the Board, in an action captioned Benjamin
Langford v. Somanetics Corporation and Gary D. Lewis.  The plaintiff alleged
that Company documents contained material misstatements and omissions in
violation of various securities laws.  The plaintiff generally sought
unspecified rescissionary damages, interest, punitive damages and attorneys'
fees.  The Company settled a class action in 1996 raising similar issues, but
approximately 11 persons, including Benjamin Langford, opted out of that action
and the related settlement and, therefore, were not barred by the settlement
from pursuing their own claims against the Company.  As a result, however, Mr.
Langford's action was no longer a class action.  The Company, the Company's
insurance company and Mr. Langford entered into a Settlement Agreement in
December 1997 that required the Company and its insurance Company to make a
cash payment to Mr. Langford.  The Company's portion of the cash payment was
immaterial, and the lawsuit was dismissed with prejudice in December 1997.

     As of November 30, 1997, the Company had employment agreements with Bruce
J. Barrett, its President and Chief Executive Officer ("Mr. Barrett"), and
Raymond W. Gunn, its Executive Vice President and Chief Financial Officer ("Mr.
Gunn"). The employment agreements, as amended, expire April 30, 2000 for Mr.
Barrett and Mr. Gunn, unless earlier terminated as provided in the agreements.
Messrs. Barrett and Gunn were entitled to receive annual base salaries which at
November 30, 1997 were $204,750 and $110,250, respectively, plus potential
discretionary bonuses. Both parties have agreed not to compete with the Company
during specified periods.

     The Company may become subject to product liability claims by patients or
physicians, and may become a defendant in product liability or malpractice
litigation. The Company has obtained product liability insurance and an
umbrella policy. There can be no assurance that the Company will be able to
maintain such insurance or that such insurance would be sufficient to protect
the Company against such product liability.


8. STOCK OPTION PLANS

     In January 1983, February 1991, and January 1997, the Company adopted
stock option plans (the "1983 Plan," the "1991 Plan," and the "1997 Plan,"
respectively) for key management employees, directors, consultants and advisors
of the Company. The plans provide for the issuance of options by the Company to
purchase a maximum of 15,668 Common Shares under the 1983 Plan, 115,000 Common
Shares under the 1991 Plan, and 295,000 Common Shares under the 1997 Plan.  In
addition, the Company granted options  to employees independent of the plans
("Non-Plan"). Awards and expirations under the 1983 Plan, 1991 Plan, 1997 Plan,
and Non-Plan during the years ended November 30, 1997, 1996 and 1995 are listed
below.

     At November 30, 1997, no additional options may be granted under the 1983
Plan, 3,577 Common Shares were available for options to be granted under the
1991 Plan, and 41,800 Common Shares were available under the 1997 Plan.

                         NOTES TO FINANCIAL STATEMENTS


     In January 1993, the Company adopted the Somanetics Corporation 1993
Director Stock Option Plan (the "Directors Plan"). The Directors Plan provides
up to 24,000 Common Shares for the grant of options to purchase 1,500 shares
every three years beginning June 30, 1993 and ending June 30, 2002, to each
director who is not an officer or employee of the Company. In addition, each
director who is not an officer or employee of the Company and who first becomes
a director of the Company after the date the Directors Plan was adopted is
automatically granted an option to purchase a pro-rata portion of 1,500 Common
Shares.

     In October 1995, SFAS No. 123, "Accounting for Stock-Based Compensation,"
was issued which encourages, but does not require, companies to record
compensation expense for the fair value of stock options and other equity
instruments granted under stock-based employee compensation arrangements.  The
Company has chosen to continue to account for stock-based compensation using
the intrinsic value method prescribed in Accounting Principles Board Opinion
No. 25, "Accounting for Stock Issued to Employees," and related
interpretations.  Accordingly, compensation costs for stock options are
measured as the excess, if any, of the market price of the Company's stock at
the date of the grant over the amount an employee must pay to acquire the
stock.  No compensation expense has been charged against income for stock
option grants.

     Had compensation expense for the Company's stock options been determined
based on the fair value of the options on the grant date pursuant to the
methodology of SFAS  No. 123, the Company's net loss for 1997 and 1996 on a pro
forma basis would have increased by approximately $901,000 to $(7,057,000), or
$(2.16) per Common Share, and increased by approximately $628,000 to
$(3,932,000), or $(2.11) per Common Share, respectively.  The fair value of
each option grant is estimated on the date of grant using the Black-Scholes
option-pricing model with the following weighted-average assumptions used for
1997 and 1996: expected volatility (the measure by which the stock price has
fluctuated or is expected to fluctuate during the period) 88.26%, risk-free
interest rate of 6%, expected lives of 4 years and dividend yield of 0%.

     The effects of applying SFAS No. 123 in this pro forma disclosure are not
indicative of future amounts.  SFAS No. 123 does not apply to awards prior to
1996.

     The Company and Gary D. Lewis entered into an Agreement and Release, dated

executive officers from time to time for two years.

     On November 6, 1996, Gary D. Lewis paid the Company $175,000 (the
outstanding principal amount of the loan at the time) in full satisfaction of
all of his obligations under the loan made by the Company to him on February 1,
1993, and the Company discharged the second mortgage and released the security
interests securing the loan and wrote off approximately $29,750 of accrued
interest with respect to that loan.

     The Company recognized no revenue in the fiscal 1997, 1996 and 1995,
respectively, from Somatek, Inc., one of the Company's former United States
distributors whose principal owner is a director of the Company. Effective
February 28, 1997 the Company terminated its distribution agreement with
Somatek, Inc.  The Company wrote off approximately $12,500, $68,000 and $0 of
trade receivables from Somatek, Inc. in fiscal 1997, 1996 and 1995,
respectively, in exchange for the return of Cerebral Oximeters.

11.  SUBSEQUENT EVENTS (UNAUDITED)

     On January 15, 1998, the Company's Board of Directors approved an
amendment and restatement of the Company's Restated Articles of Incorporation
to (i) increase the Company's authorized Common Shares from 6,000,000 to
20,000,000 shares, and (ii) remove provisions relating to the reverse stock
split effected April 10, 1997, all subject to shareholder approval at the 1998
Annual Meeting of Shareholders.

     In addition, on January 15, 1998, the Company's Board of Directors
approved an amendment to the Somanetics Corporation 1997 Stock Option Plan to
increase the number of Common Shares reserved for issuance pursuant to the
exercise of options granted under the 1997 Plan by 450,000 shares, from 295,000
to 745,000 shares, subject to shareholder approval at the 1998 Annual Meeting
of Shareholders.

     The Company is negotiating with an underwriter to underwrite a proposed
public offering, or to act as a placement agent for a private placement, by the
Company of newly-issued securities.  The offerings may be subject to
shareholder approval of an amendment to the Company's Articles of Incorporation
increasing the authorized Common Shares to 20,000,000 (the "Amendment").  Among
other things, the offering will be contingent on satisfactory completion of a
due diligence investigation of the Company by the underwriter, any private
placement investor and their agents.  Any such public offering will be made only
by means of a prospectus.  In addition, the type and amount of security, if
any, that might ultimately be issued in any such offering have not yet been
definitively determined and will be dependent on negotiations with the
underwriter, any private placement investor, market conditions and management's
then current estimate of the proceeds necessary or desired to sustain the
Company's operations.  There can be no assurance that such offering will occur
or that the Company will be able to raise any capital or capital in amounts it
desires, or on terms and conditions acceptable to the Company.

                        1998 INCENTIVE COMPENSATION PLAN

PLAN A.   All Officers and non-commissioned, full-time employees participate in
Plan A of the program.  Plan A represents 50% of the incentive compensation
potential for participants.  The basis for incentive compensation for this
portion of the program is the Company's year-to-date results versus the 1998
Sales Plan measured quarterly.  Actual pay-out is made quarterly, except for
pay-outs relating to sales exceeding 100% of the 1998 Sales Plan which are
measured and paid at year-end.

PLAN B.   Officers, and certain employees, participate in Plan B.  Plan B
represents the other 50% of the incentive compensation potential for these
participants.  For Plan B, bonuses are based on the Company's results versus
the 1998 Sales Plan, and to the extent that actual sales are at least 70% of
the 1998 Sales Plan, individuals receive incentive compensation in relation to
their achievement of individual objectives.  Measurement and actual pay-out are
at the end of the year.

PLAN C.   Those employees who participate in Plan A, but do not participate in
Plan B, participate in Plan C.  For these employees, Plan C represents 50% of
their incentive compensation potential.  The basis for incentive compensation
for this portion of the program is the individual's achievement of pre-defined
objectives.  An individual must achieve at least 50% of their objectives in
order to be receive any bonus under this portion of the program.  Actual
pay-out is not tied to the Company's sales performance and is measured and paid
at the end of the year.


PLAN A PARTICIPANTS:                    All Officers and non-commissioned,     
                                        full-time employees.

                       PROGRAM ADMINISTRATION GUIDELINES


- -    This Plan shall be administered by the Company's Compensation Committee, 
     which is authorized to interpret this plan, to make, amend, and
     rescind rules and regulations relating to this plan, to make awards under
     this plan, and to make all other determinations under this plan necessary
     or advisable for its administration.

- -    All determinations, interpretations, and constructions made by the 
     Compensation Committee shall be final and conclusive.

- -    The Board reserves the right to pay bonuses to participants beyond those, 
     if any, called for by the plan.

- -    Rights under this plan may not be transferred, assigned or pledged.

- -    Nothing in this plan confers on any participant any right to continued 
     employment and does not interfere with the Company's right to terminate an 
     employee's employment.

- -    Revenue and net income will be as reported in the Company's Form 10-Q and 
     10-K.

- -    Employee must be a full-time employee in good standing at time of pay-out 
     to receive any pay-out (i.e. no prorated pay-outs and no pay-out if 
     employee leaves between completion of period for which pay-out was 
     calculated and actual day of pay-out).

- -    Any over achievement pay-out earned due to actual revenue in excess of the 
     1998 Plan will be paid after year-end based on sales for the entire year 
     compared to the 1998 Sales Plan.  There is no cap on the bonus potential 
     for this plan.

- -    Employee participation in the program will be suspended during periods of
     sick days beyond the allowable amount, long-term disability periods, or 
     any other extended leave of absence.  Actual pay-out reductions will be 
     at the discretion of the President or the Compensation Committee.

- -    Earned pay-outs under Plan A are intended to be paid after the close of 
     each fiscal quarter based on year-to-date performance and bonuses under 
     Plans B and C are intended to be paid after the end of fiscal 1998, in
     either case as soon as practicable after sales and net income are
     determined and the bonus calculation is confirmed by the Compensation
     Committee.

- -    Payments under Plan A will be made for catching up on a year-to-date 
     basis.  For example, if the Company finishes the first quarter below
     Plan, employees can recoup their full first quarter bonus not earned by
     catching up to 100% to Plan year-to-date by the end of the second quarter.
